The New Zealand (Māori) Pioneer Battalion, or Native Contingent and Pioneer Battalion, was a battalion of the New Zealand Expeditionary Force that served during World War I. The battalion was first raised in 1915 and served at Gallipoli and the Western Front, primarily as pioneers. "By the end of the war, 2227 Maori and 458 Pacific Islanders had served in what became known as the Maori Pioneer Battalion. Of these, 336 died on active service and 734 were wounded. Other Maori enlisted (and died) in other battalions as well."
